Abstract： This article studies the feeder differential protection technology based on EPON communication for intelligent distribution networks. Firstly， the characteristics and applications of intelligent distribution network and EPON communication technology were introduced， and then the basic principles and challenges of feeder differential protection were elaborated. On this basis， a feeder differential protection system architecture and key technologies based on EPON communication were proposed， and the performance and advantages of this technology were verified through experiments， hoping to provide some reference for related work.

Keywords： intelligent distribution network; EPON communication; differential protection for feeder lines; data synchronization; fault location
